Answer :
Answer:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
-2x+2y=6,4x+2y=-5
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
-2x+2y=6
-2x=-2y+6
x=-\frac{1}{2}\left(-2y+6\right)
x=y-3
4\left(y-3\right)+2y=-5
4y-12+2y=-5
6y-12=-5
6y=7
y=\frac{7}{6}
Step-by-step explanation:
x=\frac{7}{6}-3
x=-\frac{11}{6}
x=-\frac{11}{6},y=\frac{7}{6} the answer
